Graves Exhaust System Yamaha R1 / R1M / R1S

Graves Motorsports Exhaust System Yamaha R1 / R1M / R1S

The Graves Motorsports Exhaust System was designed for the rider seeking top of the line performance, fit, finish and value. This R1 exhaust was developed using the same technology that has powered Monster Energy Graves Yamaha rider Josh Hayes to 5 consecutive AMA Superbike championships.

Graves Everlast packing produces an exhaust note like no other and holds up longer to the extreme conditions of a high-revving motorcycle. Graves incorporates advanced welding processes to reduce oversized welds that can cause excessive heat buildup. A special pipe bending technique known as mandrel bending is used for all Graves exhausts to prevent wrinkles and ovalization of the exhaust pipes. All of this combined not only streamlines the appearance of the exhaust systems but saves significant weight over the stock exhaust!

Features:

• Diamond shaped muffler design that matches the R1’s design
• Full titanium headers and mid-pipes
• Integrated exhaust hanger
• 14.4lbs lighter than stock
• 18mm O2 sensor bung
• Made in USA
